IMPROVED MACHINE POR GARBURETTING AIR.

' IO ALL' WHOll-I IT MAY CONCERN: f

Bc it known-that I, JAMES SANGSTER, -of Buifalo, in the county of' Erie, in the State of lNew York, have invented certain new and useful Improvements in und on Machines for Carhuretting Air; and I doherehy declare that the following description of the construction and operation kot` the same is sufficiently full, clear, and exact to enable others skilled in the art to which it appertaius, or to which it is most nearly connected, to make, construct, and use the same, reference being had to the accompanying drawings, making a. part oi' this specification, in which- .i A

Figure 1 is a vertical longitudinal section of my said invention.

Figure 2, a sideclevation of the air-wheel of the same.

Figure 3, a perspective view of the said wheel.'

Figure 4 represents a perspective view of the air-tube chamberwhich forms a part of said air-wheel.

The nature vof myrinventiou consists in-I First. The combination of an air-wheel with a stationary air-tube and a non-forcing air-chamber, provided with openings which rise above the surface of the water after the 'air-forcing parts or chambers ot the sdid wheel are Vclosed by the open parts of said air-forcing chambers passing into the water, the said openings in the non-forcing air-chamberbeing so arranged as to allow the air which is being forced by the air-forcing chambers Ato pass-into the said non-forcing air-chamber and air-tube, and from the said air-tube into and through the carburetting-liquiii; the arrangement being such that the air or gas is forced, as the wheel revolves,`directly through the carburetting-liquid, instead of having first to pass through water, as in other air-forcing wheels.

Second. In the combination of an inverted open-mouthed air-oating chamber or vessel Awith an air- Adischarging tube, the discharging end of which projects upward, above the surface of .the carburetting-liquid, and within the said air-Heating chamber, the weight of said air-floating chamber being so adjusted that the air will be forced into and through the surface of the carburctting-liquid down-ward the same distance, or nearly so, although the level of the surface ofthe said liquid may be changing; the pressure of the air within the said air-forcing chamber, while in action, sustaining or holding its lower edge or mouthat any distance or point to which it may be adjusted, by its weight, below the surface of the carburetting-liquid, the arrangement beingI suchthat while the machine is in action the said air-floating chamber or vessel moves up or down, as the surface of the carburetting-liquid may be moved or changed, but, at the same time, its lower edge or mouth maintains Yits proper position with respect to the surface of the same. Of course it will be readily seen that by this arrangement or device the air-floating chamber or vessel will immediately fall or Asink into thc carburettingliquid as soon as the pressure of the air is taken from it, and rise again, as soon as the pressure is renewed or air forced into it, to its proper position. v

Third. In combining with the said air-'floating chamber and air-discharging tube, a. supplemental tube, which surrounds the air-,floating chamber and projects from above the surface of the carburetting-liquid downward through said liquid to within a short distance, say ono-fourth or one halt` of an inch, of the bottom of the vessel holding thecarburetting-liquid. By .this arrangement all the liquid consumed must pass under thc lower end of said supplemental tube, so that all thc carburetting-liquid,-as it isV taken up by the nir passing through it, cornes from the lower part of the vessel holding the same.` By this means the carbnretting-liquid is kept in a. more cqualized condition, as the heavy portions of the same, which settle at the bot-toni, are taken up and mingled with the upper portions of the said liquid.

.,Fourth. My invention further consists in making the gasbmeter, into which the gas is forced,ot` a tapering forni, so that it may cause an equal pressure to be given to the gas at all times. A-s the ordinary gti-someter descends into thc water, it of course displaces a certain amount of the same, which, in the proportion of said displacement, tends to lift up ,or iloatit, thus causing less pressure o'n thevgas as it descends into the water. By my arrangement lthis defect is obviated, as the gasometer presents less surface to the gas in proportion as it descends into the liquid. Its proportions should be, say, about or nearly oneiii`teenth larger at the bottom than at the top.

In the said drawings, in which like letters represent like parts inthe several figures, A, in the section-view, represents the tapering gasometer. Its mouth or open end is sealed by water, as shown at B, into which it is moved up by the pressure of the gas.y C is the outlet-tube for the gas. D represents the air-floating chamber or vessel. It is kept up in its proper position witlirespect to the level of the earburetting-liquid, as shown by the dotted lines Gr, by the pressure of the air within it, as hereinbefore mentioned. E is the discharging end of the air-discharging tube, the discharging end of which is always above the level, Gr, of the carburetting-liqud, as shown. F2 represents the supplemental tube which surrounds the air-floating chamber D, for purposes hereinbei'ore mentioned. J is the oarburetting-liquid vessel; it is filled through 'the opening. P represents the air-forcing wheel; H, the air-forcing chambers or buckets, oi'. which there are four, two on each side. I is the non-air-forcing chamber. The letters K represent the 'openings in the same, as hereinbefore mentioned. There are four o f said openings,ltw`o on each side, placed at right angles to each other, as shown in g. 2, the` black dotted lines showing the openings on one side, and the red lines showing the openings on theopposite side, as

and for the purposes hereinbefore mentioned. F represents the receiving end of the air-discharging tube. It-

projeots up, as shown in figs. 1, 2, and 3, above the surface or level, T, of the water, so that there is no water or carburetting-liquid in any part oi' said tube, thereby leaving a clear passage for the air vthrough it, but no opening whatever for either water or' carburetting-liduid, as one end is always above'tlie water and the other above the carburettinglliquid. In fig. 3, U representsthe open sido of one of the air-forcing buckets or vessels H, and K, Within it, the position ofthe opening in the non-forcing air-chamber, showing its position-'with reference to the open parts of said openings U in the air-forcing chambers.. W,`in the samc'fignre, shows the closed back end of one of the said'cbambers H. 'The air-tube is fastened stationary at the points S S, and the air- Wheel is made to 'revalve around said tube'in the .direction of the arrows shown near the letter I, in fig. S. Motion is givento the air-.Wheel bythe usual machinery gearing into. the pinion X, and a weight.-

What I claim as my invention, and desire tosecure by Letters Patent, is

l. The combination of an air-forcing nheelwith a stationary air-tube and a non-forcing air-chamber, l, provided. with openings K, the whole lbeing constructed to operate substantially as and for the purposes herein set-forth and described. 2. The combination of an air-oating vesseL-D, and an air-discharging tube, the discharging en /.l E of which projects labove the carburetting-liquid, as and for the purposes substantially described.

3. The supplemental tube FZ, as and for the purposes substantially as described.

4. 'The tapering movable gaslholder' A, as and for the purposes substantially described.

. I JAMES SANGSTER.
